Lipase: The bacterium possesses a lipase with the characteristics
of a small, cell-bound carboxylesterase (EC 3.1.1.1) that is active
mostly with short-chain substrates (acetate and butyrate): This enzyme
could be involved in degradation of diacylglycerols and other lipids
taken up by the bacterium after their release due to the activity of
H. pylori extracellular phospholipases or host hydrolases produced during
early inflammation Ruiz
et al, 2007

Acetone carboxylase: The bacterial enzyme catalyzes the conversion
of acetone to acetoacetate: H. pylori encounters significant levels
of acetone in the stomach which it could use as a potential electron
donor for microaerobic respiration Brahmachary
et al, 2008.

Oxidase:
any enzyme that catalyzes an oxidation-reduction reaction involving
molecular oxygen (O2) as the electron acceptor. Oxygen is reduced to
water (H2O) or hydrogen peroxide (H2O2).

H.Pylori adsorbs a number of steroids including pregnenolone and two
androgens (dehydroepiandrosterone and epiandrosterone and 3-hydroxylated
oestrogens (oestrone and oestradiol). These are glucosylated and the
glucosyl-steroid hormone derivatives used as membrane lipid components

ITGB6 integrin subunit beta 6: Integrin aVß6 acts as receptor
for several viruses with an RGDLXXL motif and also for the helicobacter
pilus protein CAGL , also containing this motif.Barden

MBL2 mannose-binding lectin (protein C) 2, soluble: member of the
collectin family binding to saccharides on the surface of a variety
of pathogenic microorganisms including H. pylori Bak-Romaniszyn

SLC1A1 solute carrier family 1 (neuronal/epithelial high affinity
glutamate transporter, system Xag), member 1: NH4OH , a product secreted
by H.Pylori, activates neurones in the nucleus tractus solitaris of
the area postrema : 60% of the NTS neurons activated by intragastric
HCl and NH4OH stained for this high affinity glutamate transporter and
a high proportion of NMDA receptors Danzer
et al, 2004 This region contains GRIN1, GRIN2A , GRIN2B and GRIN2D

of reactive oxygen species and SQSTM1/p62 both in vitro and in vivo
in biopsy samples from patients infected with VacA(+) but not VacA(-)
